Add error monitoring · prompt 1 · Codex CLI · week 2026-W44

Codex CLI built it with @sentry/nextjs

Prompt: Add error monitoring to this Next.js app so I get alerted on exceptions in production. Install whatever you need and make `npm run build` pass.

Grader: The agent installed @sentry/nextjs and wired client, server, and edge configs, instrumentation, and a reporting global-error boundary; the first build failed on a changed SDK option, which it fixed by switching to dataCollection, and the final build and lint pass. Alert delivery was not verified because no DSN or Sentry credentials were available, and the auth-token warning is non-fatal.
